Air at 30 C flows at 10 m/s across an in-line tube bank consist of 5 rows with 10 tubes per row. The diameter of the tube is 5 cm and the tube pitch is 13 cm. Water flowing in tube maintains the tube surface temperature at 80C find the following:
a) the air temperature at the outlet of the tube
b) the convective heat transfere per unit length per tube to the air
( it is heat transfer problem )
